I am new to spring and log4j.I am trying a sample Hello World project with spring framework and using log4j2 library. I have log4j2.xml in my src folder. When i run the application, only my application logs are written in the log file. The spring logs are not written.However i can see them in the console. I have commons logging jar (spring dependency), log4j2 and spring jars in my classpath. Can anyone help me if I am missing any configuration here?
My log4j2 xml file,
<?xml version="1.0" encoding="UTF-8"?>
<configuration status="trace" monitorInterval="5">
<Appenders>
<Console name="consoleAppender" target="SYSTEM_OUT">
<PatternLayout pattern="%d %-5p [%t] %C{2} (%F:%L) - %m%n"/>
</Console>
<File name="fileAppender" fileName="learning.log" append="true">
<PatternLayout pattern="%t %-5p %c{2} - %m%n"/>
</File>
</Appenders>
<Loggers>
<Root level="trace">
<AppenderRef ref="consoleAppender"/>
<AppenderRef ref="fileAppender"/>
</Root>
</Loggers>
</configuration>
My Code:
public class MainApp {
static Logger log = LogManager.getLogger(MainApp.class.getName());
public static void main(String[] args) {
ApplicationContext context =
new ClassPathXmlApplicationContext("Beans.xml");
log.info("Going to create HelloWord Obj");
HellowWorld obj = (HellowWorld) context.getBean("helloWorld");
obj.getMessage();
log.info("Exiting the program");
}
}
output:
main INFO springExample.MainApp - Going to create HelloWord Obj
main INFO springExample.MainApp - Exiting the program
The spring logs are missing in the output file.
Thanks, Suma
Since the other answers don't spell it out in the actual answer, the solution is to add the Commons Logging Bridge dependency below to the Maven pom.xml file.
As stated on the Apache Log4j web page:
If existing components use Apache Commons Logging 1.x and you want to have this logging routed to Log4j 2, then add the following but do not remove any Commons Logging 1.x dependencies.
<dependencies>
...
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-jcl</artifactId>
<version>2.1</version>
</dependency>
...
</dependencies>
See the example below of the effect of adding this dependency in:
